Answer

The transformations needed are:
  • Horizontal shift
  • Reflection about the -axis
  • Vertical shift

Solution

  1. Start with the base function .
  2. The function to graph is .
  3. The transformation steps are:
    • Horizontal Shift:
      The expression indicates a shift to the right by 4 units.
    • Reflection about the -axis:
      The negative sign in front of the absolute value, , reflects the graph across the -axis.
    • Vertical Shift:
      The term at the end shifts the graph downward by 1 unit.
  4. The necessary transformations are:
    • A. Horizontal shift
    • B. Reflection about the -axis
    • F. Vertical shift

Bonus Knowledge

To transform the absolute value function into the function , let’s break it down into the necessary transformations.
First, the expression indicates a horizontal shift to the right by 4 units. Then, the negative sign in front of the absolute value function reflects the graph across the x-axis. Lastly, the “-1” indicates a vertical shift downwards by 1 unit. So, the correct transformations are:
  • A. Horizontal shift (right by 4)
  • B. Reflection about the x-axis
  • F. Vertical shift (down by 1)
That’s right for !
For graphing, start with the basic shape of , apply the horizontal shift to position the vertex at (4, 0), reflect it over the x-axis, and then lower the vertex by 1 unit to arrive at the final graph of .
Now grab your graphing tool and see how these transformations change the look of the graph. It’s like taking a standard shape and giving it a makeover! Enjoy graphing!
